what boost gauge? its probably off, especially if you are using the one mitsubishi puts in there and charges an arm and leg for.

after class i'm going to take my car to autozone to find out what code i tripped...

none of the mod i did could really make me do this could it??? let me know what you think??

i'm going to turn down my boost
Oh btw - I bet you anything that CEL is overboost if you do it 3 times or more (hit fuel cut) ... ;D

Yes you hit the over boost because you're not tuned!!!! That’s the exact same code I was throwing until I got tuned.

now, learn to listen to your Evo lords yound padwan learner.

and your boost gauge is waaay off if its saying 20.5psi.

depending on what year car you have, it takes atleast the motor seeing 22psi for 2 seconds strait to hit boost cut. this will happen most in 5th, because there is more load on the motor and it will run higher boost.

Do you have a boost gauge? with the cold weather you probably over boosted and hit fuel cut. the pop was probably a backfire right after the fuel cut.
